HOSE NOZZLE Filed July 24, 1954 WITNIII:

l, #Lulu Patented Mar. l2, 1935 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to hose nozzles and its general object is toprovide a nozzle that can be adjusted from completely opened to closedpositions to vary the stream as desired, in an easy and expeditiousmanner and with the same hand used to hold the nozzle.

A further object of the invention is to provide a nozzle of thecharacter set forth, that is leak proof, simple in construction,inexpensive to manufacture and extremely eflicient in use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure l is a longitudinal sectional view taken through the nozzle whichforms the subject matter of the present invention.

Figure 2 is a sectional view taken approximately on line 2-2 of Figure1, looking in the direction of the arrows.

Figure 3 is a sectional view taken approximately on line 3-3 of Figure1, looking in the direction of the arrows.

Referring to the drawing in detail, the reference numeral 1 indicatesthe body of my nozzle which as shown is slightly tapered toward one endwhich is interiorly threaded as at 2, while its opposite end is in theform of a collar 3 that is likewise interiorly threaded for the purposeof being threadedly connected to the end of a hose or the like.

Threadedly secured to the threaded end 2 is the outlet portion 4 of mynozzle and which includes the usual outwardly flared mouth 5 having apartition 6 arranged at the juncture of the mouth 5 with the outletportion as clearly shown in Figure l, and this partition is providedwith the usual centrally disposed opening for the passage of the reducedend 7 of the plunger 8, the latter having a spear head 9 formed on itsouter end for disposal within the mouth 5.

The plunger or piston 8 may have formed longitudinally thereon vanes 10and the inner end thereof has formed thereon a valve head 1l whichextends into the body 1 and cooperates with an elastic washer- 12 tocontrol passage between the body and the outlet portion as shown. Thewasher is disposed within a shouldered portion provided by an exteriorlythreaded collar 13 that acts to threadedly secure the outlet portion tothe body, and a gasket 14 is employed to provide a leak proof connectionbetween the outlet portion and the body, as will be apparent.

Extending rearwardly from the valve head 11 is a pair of parallelarranged arms 15 and one of these arms has secured thereto adjacent itsfree end and extending at right angles therefrom a pin 16 for a purposewhich will be presently described.

The body has a boss 17 formed thereon and laterally extending therefrom,and the boss is provided with an annular flange to rotatably receive acap 18 that is held associated therewith through the instrumentality ofa screw 19 which is mounted for movement in a slot 20 arranged in theflange as best shown in Figure 3.

The boss is provided with a bore centrally arranged therein andextending inwardly from the boss is a hollow member 21 having a reducedinner end with an opening therein, and the hollow member provides achamber for the purpose of receiving packing 22 for a shaft 23.

The bore of the boss is threaded for a portion of its length to receivegland members 24 and 25 which are disposed upon opposite sides of acollar 26 formed on the shaft as best shown in Figure 1 to hold theshaft associated within the bore and for rotation.

The gland members are preferably kerfed to receive a tool so that theycan be readily associated and removed with respect to the bore, and ofcourse it will be understood that the packing 22 prevents leakage aboutthe shaft.

The upper end of the shaft has preferably arranged transverselytherethrough a threaded bore to receive the screw 19 so that uponrotation of the cap the shaft will be rotated accordingly. The lower endof the shaft has extending therethrough the shank 27 of a fork memberand the forked end which is indicated by the reference numeral 28receives the pin 16, so that upon rotation of the shaft the plunger orpiston 8 will be reciprocated through the instrumentality of the pincarrying arm 15 and the valve 10. The shank 2'1 is of a length tocontact the other arm 15 as clearly shown in Figure 2.

From the above description and disclosure of the drawing, it will beobvious that I have provided a nozzle for a hose or the like that can beeasily and expeditiously actuated from closed to open positions to varythe stream of fluid passing therethrough, and as the nozzle is actuatedthrough the instrumentality of the cap 18 it can be controlled by thesame hand used to hold the nozzle. The velocity of the fluid iscontrolled by the valve which includes the head 11 while the spray iscontrolled by the head 9 and its relation with respect to the partition6.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

What I claim is:

1. A nozzle comprising a body, an outlet portion threadedly secured tothe body, a piston mounted for slidable movement longitudinally of theoutlet portion, a valve head formed on the inner end of the piston andarranged in the body, means for cooperation with the valve head tocontrol the passage of fluid from the body to the outlet portion, spraycontrolling means included in the piston and the outlet portionrespectively, a shaft mounted for rotation through the body,

leak proof means for said shaft, means for rotating said shaft and meansof connection between the shaft and the piston for actuating the latter.

2. A nozzle comprising a tapered body having a threaded end, an outletportion secured to the threaded end and having an outwardly flaredmouth, a piston mounted for reciprocation in the outlet portion andincluding vanes, valve means for controlling fluid from the body to theoutlet portion and including a head mounted on the inner end of thepiston, spray controlling means at the outer end of the outlet portionand including means formed on the piston, a boss formed on the body andhaving a bore extending therethrough for communication with the interiorof the body, a shaft extending through the bore and mounted for rotationtherein, leak proof means for the shaft, a cap mounted for rotation onthe boss and connected with the shaft to actuate the same, and meansextending from the piston and having connection with the shaft wherebythe piston is actuated upon rotation of the cap.
